ASP Cogs? How much boost are the ASP cogs supposed to make with a D1SC at 6,000rpm? Do they offer different boost levels? I'm looking to make about 14psi, so just wanted to know if the cogs will spin the blower to that speed.

Scott, I think the main reason yours worked and my ASP didn't was because of mine being quite a bit smaller, its 7.85", I was having really bad slipping problems with a 3.3" RR pulley......everything was alinged perfect, and had max tension on the belt, held 14psi, then nosedived, so if maybe you make the tensioner slot lower you can run even more tension, but thats got to be hard on the front of that setup........
I'm running the ASP COG setup right now, its a 73/31 tooth setup, its going to max out the D-1SC probably at 6500 rpms, I think it should make about 15-16psi at that level....You have to make the slot in your bracket where the tensioner runs opened up 1.25" so you can slide the belt on under the tensioner......so far so good this way.....
I'm having problems keeping my crank bolt in, thats because it was used 4 times previous, so I ordered a new one, and this should hopefully do the job......
Just flashing the converter in 3rd gear, it goes to 6-7psi and blows off, I'm sure its going to make some boost......HOPEFULLY

I did my tooth count..
I'm running 72 Crank and 30 Blower. I'm seeing a max of 11psi at 6400 rpms.
Scott ws6. I'm glad your not having slippage issues. But I do believe thats because you don't half to spin your F1 as hard as our P1 or D1's With your internal step up ratio of 5 to 1 VS our 4.10 to 1 does make a difference.
To see my numbers I had to go COGS. I believe I'm the only one whos making the ASP cosgs setup work so far.. I've had mine for over 1 year, and my only problem is a break my cogs belts from time to time.
